1)
For two competing species (denoted 1 and 2), the population growth rate of species 1 in the presence of species 2 is.
Lower at all population sizes of species 1 than in the absence of species 2.
Zero when the population reaches K.
Dependent on the carrying capacity of species 2.
The same as in the absence of species 2.
2)
What is the equilibrium population size of a species in the absence of competitors or predators?
All of these
The population at which the per capita growth rate = 0.
K
The maximum population size the environment can sustain.
The population size at which dn/dt=0 (where N refers to the population size).
3)
When is competitive exclusion likely to occur?
When interspecific competition is more intense than intraspecific competition.
When two species exhibit resource partitioning.
When interspecific competition is less intense than intraspecific competition.
When the inferior competitor has a refuge in the environment.
4)
If interspecific competition does not lead to the coexistence and leads to existence of a species, which species has the maximum likely chance to survive described in theory section?
Caenobita clypeatus (Herbst).
Brachymyrmex obscurior Forel.
Dorymyrmex pyramicus Roger.
None of the above.
5)
In a given habitat, the maximum chance to win in an interspecific competition is more likely for ________.
Aggressive, invasive and not a native origin.
Native, and not so much aggressive or invasive.
Both aggressive and invasive.
None of the above.
